I I TABLE LEG ASSEMBLY Filed June 19, 1957 IN V E N To R fg/o/o 14 5acco/vs My inventionrelates to a novel table leg assembly, and to a novelmounting therefore, which can be rapidly and easily secured to a tabletop. More particularly, the

invention is concerned with such a leg assembly so constructed anddesigned that a hollow table leg may be readily inserted in or removedfrom a leg mounting at will.

For some time there have been available for amateur and professional usedemountable table leg assemblies comprising a mounting which may bescrewed to a table top, after which a leg is secured to the mounting bymeans of a centrally located stud bolt, or by a series of bolts. Thefirst is fairly satisfactory for smalltables where strength and rigidityare not diflicult; the second has been used for greater strength andrigidity, but is slow and diflicult to assemble and relativelyexpensive'to construct.

Furthermore, when such an assembly has included a hollow table leg, ithas been necessary to weld their side seams'full lengtha relativelyexpensive and difiicult type of construction, particularly when the legis tapered.

In accordance with the present invention there is provided a novel tableleg assembly comprising a leg mount adapted to be secured to the bottomof a table, and comprising an outstanding flange having all parts in :acom-v mon plane for positioning flush against the bottom of a table. Aleg receptacle projects out from within the area bounded by the flangeand has a flat surface against which there is fited a cap plate formingthe top of a hollow table leg. The cap plate is held in position by apair of metal ears integral with the leg receptacle and folded over thecap plate in such a way that the cap plate may he slid into and out ofthe slots formed by the cars.

A detent of any suitable type such as a screw, spring clip or the likeis secured to both the cap plate and the leg receptacle to secure theleg rigidly to the mounting.

The hollow tapered table leg has a longitudinal seam comprising insideflanges facing away from one another, and embraced by flanges of a longmetal strip having flanges which face toward one another so that thestrip can be slid over the leg flanges and be substantially coextensivetherewith.

Further details of the.invention will be described in connection withthe annexed drawing wherein:

Fig. 1 is a perspective view of a leg mounting showing a leg cap platein position therein;

Fig. 2 is a cross sectional view taken along the line 22 in Fig. 1;

Fig. 3 is a cross sectional view taken along the line 3-3 in Fig. l;

Fig. 4 is a perspective view showing the hollow legand cap plateassembly of the invention; and

Fig. 5 is a partial cross sectional view taken along the line 55 in Fig.4.

Referring to Fig. 1, there is shown a leg mount M comprising a steelplate which is cold formed by cupping to have a hollow angularly offsetcup 11 having a flat outside surface 13. The cup 11 has a rim 15 fromall sides nited States Patent 9 Cit "ice

of which there project outwardly flanges 17 arranged in a common planefor positioning flush against the bottomv of a table. Flanges 17 arebored at spaced points for the passage of screws or bolts to secure themounting to the table top.

An angularly offset cup has been shown solely to illushate theprinciples of the invention, since it is apparent that a non offset cup,or one at a different angle can, I

also employ the present invention.

Two opposite sides of the cup 11 are parallel and the' other twoopposite sides are inclined toward one another so as to have atrapezoidal shape. A cap plate 19 of similarly trapezoidal shape restson the surface 13 and is held in position by a pair of ears 21 and 23and by a. metal screw 25 which is threaded through the registering holesin the cap'plate and the cup bottom, as in Fig. 2.

As shown in Fig. 3, the ears 21 and 23 are lanced or punched from thebottom of cup 11 at a position adjacent its sides so that the earsremain attached to the cup immediately at its sides and then are bentover in an L shape in spaced relationship to the. bottom of the cup,thereby forming slots or'grooves into which the cap plate 19 may slide.Due to the inclination of the coinciding parts, insertion and removal ofthe cap plate may be effected easily and quickly to a position such thatthe sides of the cap plate and the ears are in close contact.

Maintenance of the connection rigidly is assured by the detent screw 25.

Cap plate 19 is welded to the top of a hollow tapered metal table leg 29and projects beyond the boundaries. of the leg on all sides to assurerigidity and to provide room for the bolt hole 31. i

A longitudinal side seam 33 extends the full length of the leg 2?,but isrelatively invisible because'the edges of the leg are secured togetherinsideI The leg is formed by bending it to shape from "a single piece ofsheet metal of the desired thickness so as to have the desired taper,and the desired cross sectional shape such as triangular (shown),square, or polygonal.

Referring to Fig. 5, the edges of the formed leg are bent back uponthemselves on the inside of the leg to form oppositely extending flanges35 and 37 spaced from the inside leg surface and lying in a commonplane. The flanges 35 and 37 are held together by a long metal strip 39extending the full length of the leg and having oppo site side edgeseach bent back upon itself and forming a second pair of flanges 41 and42 which face toward one another in a common plane and are spaced fromthe main body 43 of the connecting strip a distance about equal to thethickness of the metal in leg 29. When it is desired to finish the leg,the seam is formed by abutting the side edges together and the strip 39is then slid over the flanges 35 and 37 from either the bottom or thetop (before the cap plate 19 is welded on) so that the flanges 41 and 42embrace the fianges 35 and 37 and fit within the spaces between thelatter and the inner surface of the leg.

From the foregoing detailed description it is evident that my inventionis a novel construction for making a sturdy demountable tableleg at lowcost which is rapidly and easily assembled and applied to a table top.

It is apparent that changes in the construction and relative arrangementof parts may be made by persons skilled in the art without departingfrom the principles of the invention and its scope as defined in theclaims appended hereto.
